Babyshower and BRU question

xoxtorixox92

So, I know when people buy things off your registry, all the money spent goes towards the Babies R Us rewards dollars.  However, my shower was on Saturday, and everything purchased did not qualify because you can not earn rewards till Feb 1st.  I also know Babies R Us will except returns without a receipt as long as it is on your registry.  My question is, would I be able to return my big ticket items to Babies R Us for the store credit, and then repurchase these items after Feb 1st in order to get more Rewards Dollars?  TIA
